The feature most asked for is finding the correct set of lookahead
token, to be used in an interactive parser. The error recovery thing
seems to be rather out of vogue these days, in view of very
interactive computer programming - it is fairly easy to fix the
problems and recompile. It is still important to have good error
messages, of course, identifying the point where the error occurred.#
Pretty true. One advantage of having an accurate error repairing
technique like BF, is that you get really good quality error
diagnosis,
and also most of the times you can even diagnosis correctly the
corrections for multiple errors that occur in close proximity.
